I am creating an application that writes to a log file, and I need to know how in Linux / Bash to continuously display the log file to the screen (updating the screen with every new line put into the log).
So as an example, lets say I want to push a running log of apache/error.log to the screen (ssh terminal) continuously updating.

Press Shift-F. This will take you to the end of the file, and continuously display new contents. In other words, it behaves just like tail -f. To scroll backwards, you must first exit the follow mode by pressing Control-c.
bash [filename] runs the commands saved in a file. $@ refers to all of a shell script's command-line arguments. $1 , $2 , etc., refer to the first command-line argument, the second command-line argument, etc. Place variables in quotes if the values might have spaces in them.
Running shell command or script in background using nohup command. Another way you can run a command in the background is using the nohup command. The nohup command, short for no hang up, is a command that keeps a process running even after exiting the shell.
Try the tail command:
tail -f filename Another solution is
less +F filename or just less filename and typing "F" into it (pressing shift+f). It can be better than tail, because it allows you to cancel continuous printing temporary, go backward to look something and reenable it with "F" (shift+f) again
